Four screenshots, four steps — from a bare adapter to a ringing phone.
Ready to go? Walk me through setup →The Concierge calls you when you ask. Long Distance safely connects friends, and the Operator works the board.
A world that knows where your phone lives — and what era it was made.
Tell the Concierge when, and your phone rings on its own — a wake-up on your birthday, the riddle line every evening, Jefferson every full moon. It dials you, never at the exact same second, like a hand on a pocket watch.
Safe For Kids! — Two Exchanges can now connect using a private invitation code. Kids call kids. A museum in Boston calls a gallery in New York. You dial 1 + area code + extension and hear a real voice at a real phone on the other side of the country. Remove the connection and it's gone — no trace, no lingering access.
She hunts for open trunk lines. She celebrates a new long-distance connection like it's your birthday. She narrates the small drama of putting a call through. She asks if there's anything else before she signs off — then actually hangs up. She's not reading a script. She's working the board.
Story time asks who it's talking to before the story begins. Jefferson conducts a real dialogue set in the founding era. Actors and weather reporters know the year of your phone and respond from inside it. Every call is unique because every caller is.
Pickup click. Hang-up thud. The faint crackle of a live circuit. Every sound is sourced from real telephone recordings — not synthesized effects. When someone picks up, it sounds exactly like the era of their phone.
Your weather is your weather. Your Operator knows your city. Area codes are assigned by real geography — Boston gets 617, New York gets 212. The world your Exchange lives in matches the world of your imagination.
Real-time audio over RTP — voice flows continuously and naturally, the way telephone conversations have always worked. No gaps, no waiting. Latency you won't notice. Quality you will.
Your own, personal network.

Not a recording. A live voice that listens, responds, and transfers your call — just like a real operator would.
Build an Operator, a weather line, a Shakespeare quiz, a family hotline. Every service has its own voice, era, and personality.
Each phone has its own Era. Each service has a voice and vibe. Live data — weather, news, trivia — flows in automatically, making every call unique.
Perfect for museums, children's play facilities and of course, your own living room.
Learn MorePhones don’t dial the outside world — they dial your world. POTSBox creates a private phone network where every phone can call every other phone in your home, your favorite AI services, and — with a simple invitation — a friend's vintage phone collection across the country.
Every phone can have its own personality. A 1940s rotary might reach a 1940s weather reporter. A 1970s push-button might connect to a cheerful Operator. You decide what every number does, then customize it all from a simple web console — no programming required.
Calls between your phones are always free. Special AI services like the Operator, Story Time, and the Weather Line use a small coin balance, just like dropping a coin into an old payphone.
Sign up for free. Your Exchange is live immediately — pick up and dial.
Three Ways To Connect:
Get Your POTSBox Choose the POTSBox that's right for your collection. Connect your vintage phone and your home Internet, and your Operator activates your account. That's it. Your phones are ready to ring, call each other, and explore the world you create. Use app.pots-box.org to customize your Exchange, add phones, manage numbers, and personalize your Operator and AI services.
Try it now — no hardware at all. Download Telephone for Mac (free) or any SIP app on your phone. Enter your SIP credentials from the console and you’re on your Exchange in under a minute. Good for trying it out or testing a new service.
Go fully analog — the hacker thing. Connect through an any ATA adapter (Grandstream HT801, ~$40 on Amazon). Plug into your router and follow the four-step setup walkthrough — your 1940s bakelite is alive again.
Calls are free. Services use coins.
Dialing another phone on your Exchange — or a friend’s Exchange on the other side of the globe — costs nothing. AI Services — the Operator, the weather line, the storyteller, Jefferson — draw on prepaid balance. Think of it like a payphone. You add credit when you need it. No subscription, no monthly bill. An ATA or Analog Telephone Adaptor is required to connect your phone to the service, this is the POTSBox or bring your own and configure yourself, it's simple.
Rates and availability are subject to change. POTSBox AI services depend on upstream providers; we cannot guarantee uninterrupted availability. See our Terms of Service.
ATA (Analog Telephone Adapter) is a device that allows traditional analog phones (like your old rotary or push-button phone) to connect to modern digital services.
SIP (Session Initiation Protocol) is the technology that allows your phone to communicate over the internet.
